Sanvitalia procumbens shots using the CERCO 94mm lens, mod. Xenon flash, ISO200/400, 1/125s, f5.6. The needed adjustments were done by adjusting the flash energy and using a ND filter for the VIS shot.
Baader UV/IR CUT filter (VIS):
XBV3-filter (BV bee vision):
Baader U - filter (UV):
Interesting to note, that the lower flower has much less of an UV pattern maybe denoting a different ripening status?
Stay tuned, more will follow on that fascinating subject...
